## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability api-deepbluebase-xyz-b844b305
```

Example prompt: What's the current sentiment and technical regime for BTC, ETH, SOL, and XRP — are they trending up or down, what does the RSI and whale flow look like, and how confident is the signal?

## When to prefer this

Choose this endpoint when you need a multi-asset sentiment composite combining technical indicators (RSI, MACD, Bollinger), regime detection, whale flow, and fear/greed into a single scored output for BTC, ETH, SOL, and XRP simultaneously. Prefer this over single-asset or single-indicator endpoints when you want a holistic, LLM-ready signal without assembling data from multiple sources.

## Known failure modes

- Payment not included or insufficient — returns 402 Payment Required
- Upstream data source unavailable — may return 503 or partial data
- Rate limit exceeded — returns 429 Too Many Requests
- Malformed request — returns 400 if required fields are missing

## How this service works

Crypto sentiment composite: BTC/ETH/SOL/XRP technical indicators, regime detection, and sentiment scores

## Output

Returns an array of per-coin objects (BTC, ETH, SOL, XRP) each containing: RSI, MACD histogram, Bollinger %B, market regime (e.g. trending/ranging), directional bias (UP/DOWN), composite sentiment score and label, confidence score, whale flow score with buy ratio and source, normalized fear/greed and momentum sub-scores, and counts of bullish/bearish/neutral indicators. Also includes an overall market_sentiment summary object.
